Passage Summary: The government is allowed to stop you from doing something only if you're likely to hurt someone else and you aren't trying to be helpful.

Reasoning: The principle establishes two necessary conditions for justified government interference: the action must increase the risk of physical harm to others, and the action must not be motivated by a desire to help others.

Analysis: This is a 'Sufficient Condition' application. For the government's interference to be 'justified,' we must satisfy both requirements: (1) risk of physical harm to others AND (2) no altruistic motive. When looking at the answer choices, ensure both boxes are checked before the 'justified' label is applied. Be wary of choices where the government interferes with someone who *is* trying to help, or where the harm is only to the person themselves, as those would not fit the specific criteria provided in the stimulus.
